COURSE NUMBER: AGRI180
COURSE TITLE:Introductory Soil Science
DIVISION:Technology
IAI CODE(S): AG 904
SEMESTER CREDIT HOURS:4
CONTACT HOURS:75
STUDENT ENGAGEMENT HOURS:180
DELIVERY MODE:In-Person

COURSE DESCRIPTION:
New technology has allowed more accurate mapping (GPS, GIS), soil identification, and fertility of soils which operators along with soil scientists can use to evaluate soil conservation and production factors. The course covers chemical, biological and physical properties of soils such as their origins, classification and distribution. Soil Science has an influence on agriculture economics, food production, conservation and an environmental impact as a limited resource. Current and new technology, along with an ever increasing population make it essential that the students comprehend the importance of maximizing production our soils while utilizing sustainable practices.

PREREQUISITES:
Completion of or current enrollment in CHEM100.

NOTES:

STUDENT LEARNING OUTCOMES:
Upon completion of this course, students will be able to:
  • Develop an understanding and knowledge of the basic and applied chemical, physical and biological concepts in soils.
  • Develop an understanding of the origin classification, and distribution of soils and their relationship to man and food production.
  • Develop an understanding of the management and conservation of soils.
  • Develop an understanding of the environment impact of soil use.
